Figs grown under glass frequently become diseased and rot when about half-ripe. The free end of the fruit presents a waterlogged appearance. This is quickly followed by the appearance of a dense mouse-grey mould, and the entire fruit soon collapses with a wet rot and becomes entirely covered with the mould. When the trees are supplied with an excess of nutrition, the half-ripe "fruit" often emits a small amount of a sweet fluid through the pore or opening at its apex. The spores of the fungus readily germinate in this liquid and attack the fruit itself. In this case the action of the fungus is secondary, its presence being favoured by the overfed condition of the plant. [g. m.]
Four scale insects attack the Fig now and again under glass, but seldom do much harm, and can easily be kept down by hand treatment with paraffin washing. The insects are the Soft Brown Scale (Lecanium hesperidum), the Camellia Scale (Aspidiotus camellice), the Narrow Fig Scale (Lepidosaphaes ficus), and the Long Black Scale (Ischnaspis fili-formis). Thrips, Mealy Bug, and Red Spider may also attack Figs.
